Holding Devices for Ty e-Writers, ofwhich the following a speci cation accompanied.

by drawings.

This invention 4relates t0 improvements in card-holding devices for type-writers; -and the objects of the invention are to improve on suchdevices and enable the cylindrical litten of the machine to be utilized for both paper and cards without'l altering or removing any of the parts.

Another object of the invention is to secure a smooth'unbroken surface on the platen all of the same character for the use of paper when the card-holding deyi'ce is not in use.

My improved card-writing device is de- -signed for adaptation to the vcylindrical platen of any type-writing machine and is' not confined to any special type of machine, so thatthe invention' is, 'in fact, a universal attachment for type-writers simple and efficient in construction. and operation and cheap and strong and not liable to get out of. order.

V The invention consists of a card-holding device for carrying out the above objects embodying the features of construction, combinations of elements, and arrangements of parts having the general mode of operation substantially as hereinafter fully described and claimed in this'speci'lic'ation and shown in the accompanying drawings, which- Figure 1 is a perspective view of the card; holding attachment to be applied to ai cylindrical platen. Fig. 2 is a Fig. 6 is a plan view of the platen on' reduced' scale.

Referring to the drawings, A represents a' hollow cylindrical-platen for a type-writing machine provided with my' improvement.

` holdingclamp satisfactorily and well.

ongitudinal sec-,j tional view through theplaten and attach-- The surface of the platen is formed of hard.

rubber B or other suitable material, as in the usual construction, and a slot C is cut in the walls of the platen and through the rubber surface coverm in order to enable the card.- A

`ed'through the walls of the platen.

The `card-holding clamp D is 'preferabiy provided with a surface E similar to that of the platen, and when the clamp is in retractto be projected and retracted position it. preferably lies the slot C w. gh the surface E substantially flush 'with the surface B ofthe platen,s'0 that a substan-l tially unbroken surface Aall of the same character is rovided for the platen, thereby enabling tle same platen to be used for.' paper or cards without alteration or removal of any of the parts of the card-holding device.

Any suitable means maybe provided for projecting and retracting the card-holding clamp D and in this instance an efficient and preferable construction is shown in the drawings which has been found to operate Upon the platenshaft F is arranged a loose sleeve G, to which the clam Dis suitably pivoted, as by means of the coilars H, secured to the sleeve, in this instance by set screws i As shown, the clamp D is secured to a bar J by any suit able means, as the holdingdevice or evices K and rivets L; but I am not to'be understood as limiting myself to the apparatus disclosed, and the ends of the bar J are inserted in holes inthe flanges of the-collars H, so that the clamp D may have movement relatively to the collars.

. 1 When placed in position-in the platen, the

clamp D projects into the slot C, and suitable means are provided at the exterior of Athe platen or roll for rotating the sleeve G, and

with thecollars H, so that the clamp Dis moved outwardly and projected through the slot- Cin the platen, in which case the tensionsprings O, connecting the clamp and the sleeves H, tend to draw the clamp transtends to retract the clamp D when the hooked end of the clamp is primed irs/*ey from the odge ci the slot C in the pieten, ei thor by hand or by turning the pleiten until the projecting end of the cle-nip D ebuts against the longitudinal measuring-ber of the machine, in which cese the clamp D sncps beck. into retracted position in the slot C.

ln order to rotate the sleeve D, es shown', e sleeve 'U is connected fest thereto end-prom vided with e erenked arm V, adapted to project through slot N in the end disk X of the platen en( adapted to have secured thereto the thumb piece Y, es by means of thescrevv Z.

The end disks S and X are secured fest to the body portion of the platen, and the disk X is provided with e thumb-piece X. It will be seen that when the thumb-pieces Y and X ere pressed together the clamp D Will be projected into position for holding e card. According to thisinvention the operative parts connected to operste the clamp D form a spring-controlled toggle-actin@P mechanism, of which th'e clemp Diorms one eg, having en AContinent against the edge of the slot C, end the levenerm, comprising the thumb'piece Y, cre-nk V, and sleeves U, G, and H, forms the other leg of the toggle to is pivoted. The thumb by moving the thumb acting mechanism is clamp D.

Preferably the projecting lip or ilenge on the clemp D is curved on its upper end under sides to conform to the curvature of the sur fece of the pieten.

In Fig. i e n'icdiiibetion is shown in which e longitudinally-extending portion c of the platen-Wall is hinged et a and suitebly connected to the plete D, the rem einin ports of the device being like those elreedy oeecribed. lil/"hen the thumb-piece Y is opereted, it will be seen that the hinged portion C of the .platen Will be reised and lowered to permit a, cord P to be clamped,
